Terminal-Based Subscriber Audits

The `list_subscribers` tool lets Claude Code query your reader database directly from the command line. SREs and developers can pipe this output into local grep or awk scripts to audit active accounts. You do not need a heavy web interface to check your audience size. Running a single command lets you inspect subscriber profiles and export the results to your terminal buffer.

Scripted Newsletter Dispatches via CLI MCP Server

The `create_email` tool allows Claude Code to draft and queue new emails using local terminal inputs. You can feed raw markdown files from your git repository straight into the tool. This makes automated release notes incredibly simple to distribute. Your build pipeline can trigger the CLI to draft a newsletter the moment a new tag is pushed.

Automated Webhook Diagnostics

The `list_webhooks` tool gives Claude Code the capability to monitor active event listeners from your shell. This MCP tool helps you verify if your endpoints are registered. If an endpoint is missing, the agent runs `create_webhook` to register the new destination. You manage your entire pub-sub architecture without leaving your SSH session.
